Specification of Letters Patent.

Patented June 23, 1908.

Application filed m a, 1907. Serial No. 382,800.

T0- all whom it may concern:

Be it known that I, ROBERT WOERNER, engineer, a subject of the Grand Duke of Baden, residing at Mannheim, Luisenrin 54, in the Grand Duchy of Baden, German mpire, have invented a new and useful Wash- Ing-Machine, of which the following is a specification.

My invention relates to im rovements in washing machines of that kin in which a revolving drum lifts the Wash out of thewater, allows the Water absorbed by the wash to run off together with the dirt separated from the wash, after which said wash is again thrown into the Water. In consequence of I the continued rotation of the drum, the Wash is again ,steeped in water and then raised, only to fall back into the liquid which process is continued till the wash is clean.

While the wash is nearly out of the water it can be passed over smooth or rippled surfaces which may be movable or immovable. The friction of'the wash with these surfaces sep arates mechanically such pieces of dirt that stick fast to the Wash.

The object of my invention is attained by using a drum which is notcylindrical but is recessed in such manner that each of its recesses is made large enough to contain the Whole of the washwhich it is intended to clean.

My washing machine containsa second inner drum within the outer drum. Between these, brushes are arranged, over which the wash must pass when it is thrown from one recess of the outer drum into the next. By this method the wash is thoroughly cleaned in all its several parts.

In the accompanying drawing: Figure 1 is a verticalcross-section of the drums of a washing machine constructed in accordance with my invention. Fig. 2 is a similar view of a modified construction, and Fig. 3 is a broken detailed view showing one way of mounting the drums in Fig. 2 so that the outer one will revolve and the inner one remain stationary.

Within a fixed cylinder a having a lid 1) is arranged a revolving Washing drum 6., the surface of which is formed in such manner as to produce four se arate recesses or chambers 1, 2, 3 or 4, t e vertical section of the drum thus resembling a cross. A lid f allows of the filling and emptying the drum. Its surface may be perforated with holes or slotted according to circumstances.

Referring first to Fig. 1, the outer drum e is made of corrugated sheet metal such as galvanized iron. Within said outer drum is arranged another drum 9 which is cylindrical and also constructed of corrugated sheet metal. Both drums are mounted to revolve on the shaft h. One or more rotary brushes 3 are secured to the inner surface of the outer rum at the juncture of two of its compartments. The axle c of each of said brushes is mounted to slide in angular slots comprising branches 8 and t in the bearing plates (1.

In Fig. 2 the outer drum 6 is constructed of narrow spaced apart laths of wood or other suitable material as is also the inner drum 9 which is formed like a half cylinder. Said inner drum is fixed to the rigid shaft b while the outer drum is adapted to be revolved. In Fig. 3 I have illustrated one construction whereby this result may be obtained but any other arrangement may be em loyed which will answer the purpose. Brus es g are im movably secured to the drum e at points corresponding to those on the drum e in Fig. 1 at which the rotary brushes g are fastened. Brushes of either form may be secured to the inner drum of either construction, if desired. The function of said brushes is to engage the wash as it passes from one compartment of the outer drum to another.

My washing machine acts in the following manner: The outer drum being in such position that chamber 1 is uppermost, the wash is introduced into chamber 1 through the o enings and the lids f and b then closed.

he drum then revolves by suitable means in one direction for instance in the direction of the arrow. The wash is immersedin the water, passes through it and is raised back to its origlnal position after the drum has been revolved the necessary number of times. The wash is brushed at the same time by the brushes 1 or The direction of the revolution o the d rum can be changed durin the operation, as this materially assists the 0 caning of the wash. When the drum moves in the direction of the arrow the axle c of the brush g is pushed into the slit t. If rotated in the op osite direction, the axle 0 moves into the s it s. In the drawing the relative position is shown in which the chamber 1 is adapted to allow the wash to ass into the chambers 3 and 4 after having een brushed and rubbed by the inner and outer drums and the brushes. The speed is also of importance as by it the wash can be either thrown against the wall of the outer drum -(high speed) or lies on the inner drum (low speed). When the Wash is sufiiciently cleaned it is taken out again.

What I claim as my invention and desire to secure by Letters Patent is:

1 In a washing machine, the combination,

I with a stationary receptacle, of a revoluble 4 and a brush secured to one of said drums and arranged to engage the wash as it passes from one compartment of said outer drum to another. t

2. In a washing machine, the combination, with a stationary receptacle, of a revoluble drum arranged therein and having a plurality of radial compartments, each of which is large enough to contain the whole Wash, a second revoluble drum mounted within the first drum and a brush secured to one of said drums and arranged to engage the wash as it passes from one compartment of said outer drum to another.

3. In a washing machine, the combination, with a stationary receptacle, of a revoluble drum arranged therein and having a plurality of radial com artments, a second drum I mounted within t e first drum, and a brush mounted on said outer drum at the juncture of two of its compartments and extending said drums being made of corrugated metal,

.and a brush secured to one of said drums and arranged to engage the Wash as it passes from one compartment of said outer drum to another.

5. In a washing machine, the combination, with a stationarymeceptacle, of a revoluble drum arran ed therein and having a plurality of radia compartments, each of which is large enough to contain the whole wash, a second drum mounted within the first drum, and a rotary brush secured to one of said drums and arranged to engage the wash as it passes from one compartment of said outer drum to another.

6. In a washing machine, the combination, with a stationary receptacle, of a revoluble drum arran ed therein and having a plurality of radia compartments, a second drum mounted within the first drum, and a rotary brush mounted on said outer drum at the juncture of two of its compartments and having its axle arranged in angular slots in bearing plates for the purpose specified.
